Specification of Letters Patent.

Patented June 16, 1914.

Application filed December 8, 1913. Serial No. 805,311.

To all whom it may concern:

Be it known that I, CHARLES E. WARD, a citizen of the United States,residing at Trousdale, in the county of Pottawatomie and State ofOklahoma, have invented certain new and useful Improvements in Cultivators, of which the following is a specification.

The present invention relates to improvements in cultivators, and isdesigned particularly to furnish sets of teeth that are detachable fromthe implement and may be replaced with facility and ease.

The primary object of the invention is the provision of detachabledevices for use with cultivators, that are adapted for cultivating thesoil either on a bed or in a listed furrow, and each device itself,which is easily attachable and detachable, also comprises adjustableparts for converting it to suit different circumstances.

The invention consists essentially in certain novel combinations andarrangements of parts whereby the device is adjusted and by which theteeth are held or clamped in proper position.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention constructed according to thebest mode I have so far devised for the practical application of theprinciples of my invention.

Figure 1 is a plan view of a cultivator showing my improved attachmentapplied thereto. Fig. 2 is a side elevation, enlarged, partly in sectionshowing one of the pair of devices. Fig. 3 is a front elevation of Fig.2. Fig. 4c is an enlarged detail plan view.

My attachment is adapted for use in connection with any of the usual orstandard types of implements of the cultivator class, and in Fig. 1 Ihave illustrated, only for convenience in showing the adaptation of myattachments, a type of riding cultivator which comprises the frame 1,axle 2, wheels 3, draft gear or rigging 4L, seat 5, and braces 6, 6, asusual. These parts form no part of my invention, but are designated toillustrate the applicability of my invention, and it will of course beunderstood that my attachment may be used with other and numerous typesof implements for cultivating the soil. My attachments are directlyconnected to the beams 7, 7 carried by the frame 1 of the implement, anda convenient mode of attaching is to use the U-bolts 8 which secure theupright or post 9 to the beam as shown, but of course other suitableattaching means may be employed to rigidly hold the post 9 to the beam,if desired.

A pair of the attachments completes a set, one to be attached at eachside of the implement, and it will be noted that they are reversible, orinterchangeable. Each attachment comprises the post 9 which is formedwith an angular base 10 perforated to accommodate the bolts 11 and 12,and having an integral flange 13.

The angular base 10 is designed to support the spring teeth 14 of thecultivator, which as illustrated in the drawings are scratchers of wellknown type. Each tooth is provided with a flattened shank 15 which isclamped between the base plate 16 and the cap plate 17 by bolts 18,except the central tooth which is held by bolt 12. The plates and shanksare perforated for the passage of the bolts and by means of the nuts 19the shanks are securely held between the plates as shown. An extension20 having a slot 21 extending in a curve with the bolt 12 as a center,projects backward from the plate 17 and it will be seen that the clampedteeth may be swung around the bolt 12 as a pivot, to desired adjustedposition, and then by turning nut 22 on bolt 11 the parts will be heldin adjusted position.

Having thus fully described my invention, What I claim is Thecombination, in a cultivator with a post having an angular perforatedbase, of a base plate, a cap plate and teeth having shanks between saidplates and said plates and shanks perforated for the accommodation ofclamping bolts, said cap plate having a slotted extension, and a pivotbolt connecting the base and plates whereby the teeth may be adjustedrelatively to the post base.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES E. WARD.
